cmd/link: fix log formats for log.Fatal calls

link contains many calls to log.Fatal, but it uses the default log output
format, which is configured for server programs, not command-line tools.
Set it up for command-line tools instead.

Changes errors like

2023/06/12 14:32:24 reference to undefined builtin "runtime.gcWriteBarrier" from package "internal/abi"

to
